Moreover, the invention relates to a process for preparing these compounds, to compositions comprising 2-pyrimidines and to their use for controlling phytopathogenic harmful fungi.

Fungicidal pyrimidines carrying a cyanamino substituent in the 2-position are known from WO-A 01/96314. Furthermore, fungicidal 2-pyrimidyl-N-methoxyamidines are known from WO-A 03/43993.

However, in many cases the activity of the abovementioned pyrimidines is unsatisfactory. It is an object of the present invention to provide compounds having improved activity.

We have found that this object is achieved by the pyrimidines of the formula I defined at the outset. Moreover, we have found processes for their preparation and compositions comprising them for controlling harmful fungi.

The compounds I can be obtained by different routes.

-   1) It is possible, for example, to use sulfones of the formula 11     whose preparation is described in detail in WO-A 02/074753 or DE     10156279.9 as starting materials. Reaction of the sulfones II with     metal cyanides III (Me⁺CN⁻) yields the nitriles IV. Metal cyanides     are to be understood as meaning primarily alkali metal cyanides or     alkaline earth metal cyanides or else covalent cyanides, such as tin     tetracyanide.

The exchange of the sulfonate group for the nitrile group is carried out by methods known from the literature, as described, for example, in WO-A 03/043993.

The further synthesis can be carried out as shown in Scheme 1:

The nitrile compound IV can be hydrolyzed to the amide IA under acidic or, preferably, basic conditions. The hydrolysis is carried out, for example, under the conditions described by Katritzky et al. in Synthesis 1989, pp. 949-950 (hydrogen peroxide, base, polar aprotic solvent). Hydrolyses of nitriles to amides under acidic conditions are described in Comprehensive Organic Chemistry, Vol 2, Sutherland, I.O. Pergamon Press, Oxford, 1979, p. 964.

Alternatively, the Pinner adduct, which is generated when in general hydrochloric acid forms an adduct with nitrile IV, can be reacted with an alcohol of the formula R^(b)OH, where R^(b) is as defined above, to give the imino ether of the formula IB. The alkylation with R^(a)X—Y, where R^(a) and the bridge X are as defined above and y is a leaving group such as halide, sulfate or sulfonate, gives compounds of type IC.

The alkylation with R^(a)—Y starting with compound IB or the nitrile IV can also be carried out using Meerwein salts of the formula (R^(a))₃OBF₄ analogously to the procedures given in Synth. Commun., 1983, 13, p. 753 or Helv. Chim. Acta, 1986, 69, p. 1224. This affords compounds I in which X is a direct bond.

An alternative synthesis of the compounds IA according to the invention is shown in Scheme 2.

The synthesis, shown in Scheme 2, of the compounds IA′ and IC in turn uses nitrile IV as starting material. The nitrile IV can preferably be prepared under acidic conditions in the presence of alcohols of the formula R′OH, where R′ is C₁-C₈-alkyl, C₂-C₈-alkenyl, C₂-C₈-alkynyl or C₃-C₆-cycloalkyl, where the radicals alkyl, alkenyl and alkynyl may be partially or fully halogenated and may carry one to three groups R^(v). The reaction of V with amines to give the amides IA′ can be carried out as described in Org. Lett., 2001, Vol 3, p. 1053-56 or in J. Org. Chem., 2000, Vol 85, p. 8415-20. The subsequent reaction with Meerwein salts of the formula (R^(b))₃OBF₄ analogously to the procedures given in Synth. Commun., 1983, 13, p. 753 or Helv. Chim. Acta, 1986, 69, p. 1224 yields the compounds of the formula IC according to the invention. The imine halides of the formula VI where Hal is halogen and in particular chlorine or bromine can be obtained analogously to Synthesis, 1991, Vol 9, p. 750-752. In an Appel reaction using, for example, carbon tetrabromide and triphenylphosphine, the corresponding bromine compounds are prepared. The latter can finally be reacted with alcohols of the formula R^(b)OH and base to give the compounds IC according to the invention.

The radical R³ (in particular alkyl) in the 6-position on the pyrimidine ring can be introduced by reaction with transition metal catalysis, such as Ni or Pd catalysis. In some cases it may be advisable to change the order and to introduce the substituent R³ prior to the substituent NR¹R².

In the formula (R³)_(y-w)X_(w)-M^(y), M is a metal ion of valency Y, such as, for example, B, Zn, Mg, Cu or Sn, X is chlorine, bromine, iodine or hydroxy, R³ is preferably C₁-C₄-alkyl and w is a number from 0 to 3. This reaction can be carried out, for example, analogously to the following methods: J. Chem. Soc., Perkin Trans. 1 (1994), 1187, ibid.1 (1996), 2345; WO-A 99/41255; Aust. J. Chem. vol. 43 (1990), 733; J. Org. Chem. vol. 43 (1978), 358; J. Chem. Soc., Chem. Commun. (1979), 866; Tetrahedron Lett. vol. 34 (1993), 8267; ibid. vol. 33 (1992), 413.

The substituent R^(a) in formula IA′ can also be introduced as shown in Scheme 4.

Here, the compounds of the formula IA are initially converted with the aid of strong bases into the anion and then reacted with the corresponding acid chlorides to give IA′ (see J. Chem. Soc., Perkin Trans I, 1995, p. 3043). This gives compounds in which X is a C═O bridge. Bases suitable for preparing the anion are, for example, sodium amide and sodium hydride.

What was said above refers in particular to the preparation of compounds in which R³ is an alkyl group. If R³ is a cyano group or an alkoxy substituent, the radical R³ can be introduced by reaction with alkali metal cyanides and alkali metal alkoxides, respectively.

The scope of the present invention includes the (R) and (S) isomers and the racemates of compounds of the formula I having chiral centers.

Hereinbelow, the embodiments of the invention are described in more detail.

With a view to the intended use of the pyrimidines of the formula I, particular preference is given to the following meanings of the substituents, in each case on their own or in combination:

Preference is given to compounds I in which R¹ is C₁-C₆-alkyl, C₁-C₆-haloalkyl, C₂-C₆-alkenyl, C₂-C₆-alkynyl or C₃-C₆-cycloalkyl and R² is hydrogen.

Especially preferred are compounds I in which R¹ is C₁-C₆-alkyl, C₂-C₆-alkenyl or C₁-C₆-haloalkyl branched in the α-position.

In addition, preference is given to compounds I in which R¹ is C₁-C₄-haloalkyl and R² is hydrogen.

Moreover, preference is given to compounds I in which R¹ and R² together with the nitrogen to which they are attached form a five- or six-membered ring which may be interrupted by an oxygen atom and may carry one or two C₁-C₆-alkyl substituents.

Especially preferred are groups NR¹R² such as—in particular in the α-position—methylated pyrrolidines or piperidines. Preference is furthermore given to 4-methylpiperidine.

Especially preferred are pyrimidines I in which the substituents L¹ to L⁵ are as defined below:

-   L is halogen, cyano, C₁-C₈-alkyl, C₁-C₆-alkoxy, —C(═O)—O-A,     —C(═O)—N(A′)A,     -   A, A′, A″ independently of one another are hydrogen,         C₁-C₆-alkyl, C₂-C₆-alkenyl, C₂-C₆-alkynyl.

Moreover, preference is given to pyrimidines I where the phenyl group substituted by L_(n) is the group B

where # is the point of attachment to the pyrimidine skeleton and

-   -   L¹ is fluorine, chlorine, CH₃ or CF₃;     -   L²,L⁴ independently of one another are hydrogen, CH₃ or         fluorine;     -   L³ is hydrogen, fluorine, chlorine, bromine, cyano, CH₃, SCH₃,         OCH₃, SO₂CH₃, CO—NH₂, CO—NHCH₃, CO—NHC₂H₅, CO—N(CH₃)₂,         NH—C(═O)CH₃, N(CH₃)—C(═O)CH₃ or COOCH₃ and     -   L⁵ is hydrogen, fluorine, chlorine or CH₃.

Particular preference is also given to compounds I in which R³ is C₁-C₄-alkyl which may be substituted by halogen.

Moreover, particular preference is given to compounds I in which R³ is halogen, cyano, C₁-C₄-alkyl or C₁-C₄-alkoxy.

Especially preferred are compounds I in which R³ is methyl, cyano, methoxy or in particular chlorine.

Suitable with a view to their fungicidal action are pyrimidines of the formula I in which R⁴ is

Preference is furthermore given to pyrimidines of the formula I in which R⁴ is

Especially preferred are pyrimidines of the formula I in which R⁴ is

Finally, R⁴ may preferably have the following meanings which may also be interpreted as definitions of prodrug radicals (see Medicinal Research Reviews 2003, 23, 763-793, or J. of Pharmaceutical Sciences 1997, 86, 765-767):

The index n in the alkenylene radicals of the above formulae is an integer from 1 to 3. Especially preferred are the following radical definitions R⁴:

The bridge X is preferably a direct bond or —(C═O)—.

The substituent R^(a) is preferably hydrogen, methyl, benzyl, trifluoromethyl, allyl, propargyl or methoxymethyl and particularly preferably hydrogen.

The substituent R^(b) is preferably hydrogen, C₁-C₆-alkyl or C₂-C₆-alkenyl and particularly preferably: methyl, allyl or propargyl.

The substituent R^(c) is preferably hydrogen or methyl.

The esters of the formula V

are both interesting intermediates and excellent fungicidally active compounds.

The preferences in the definitions of L_(n) and R¹ to R³ mentioned above apply correspondingly to the esters of the formula V.

R′ is in particular a C₁-C₆-alkyl radical, especially preferably an isopropyl radical.

However, R′ may also have the meanings allyl, propargyl, benzyl, aminoalkyl, hydroxyalkyl, alkoxyalkyl or haloalkyl.

In particular with a view to their use, preference is given to compounds I and V compiled in the tables below. Moreover, the groups mentioned for a substituent in the tables are per se, independently of the combination in which they are mentioned, a particularly preferred embodiment of the substituent in question.

The compounds I are suitable as fungicides. They are distinguished by an outstanding effectiveness against a broad spectrum of phytopathogenic fungi, especially from the classes of the Ascomycetes, Deuteromycetes, Oomycetes and Basidiomycetes. Some are systemically effective and they can be used in plant protection as foliar and soil fungicides.

They are particularly important in the control of a multitude of fungi on various cultivated plants, such as wheat, rye, barley, oats, rice, corn, grass, bananas, cotton, soybean, coffee, sugar cane, vines, fruits and ornamental plants, and vegetables, such as cucumbers, beans, tomatoes, potatoes and cucurbits, and on the seeds of these plants.

They are especially suitable for controlling the following plant diseases:

-   Alternaria species on fruit and vegetables, -   Bipolaris and Drechslera species on cereals, rice and lawns, -   Blumeria graminis (powdery mildew) on cereals, -   Botrytis cinerea (gray mold) on strawberries, vegetables, ornamental     plants and grapevines, -   Erysiphe cichoracearum and Sphaerotheca fuliginea on cucurbits, -   Fusarium and Verticillium species on various plants, -   Mycosphaerella species on cereals, bananas and peanuts, -   Phytophthora infestans on potatoes and tomatoes, -   Plasmopara viticola on grapevines, -   Podosphaera leucotricha on apples, -   Pseudocercosporella herpotrichoides on wheat and barley, -   Pseudoperonospora species on hops and cucumbers, -   Puccinia species on cereals, -   Pyricularia oryzae on rice, -   Rhizoctonia species on cotton, rice and lawns, -   Septoria tritici and Stagonospora nodorum on wheat, -   Uncinula necator on grapevines, -   Ustilago species on cereals and sugar cane, and -   Venturia species (scab) on apples and pears.

The compounds I are also suitable for controlling harmful fungi, such as Paecilomyces variotii, in the protection of materials (for example wood, paper, paint dispersions, fibers or fabrics) and in the protection of stored products.

The compounds I are employed by treating the fungi or the plants, seeds, materials or soil to be protected against fungal attack with a fungicidally effective amount of the active compounds. The application can be carried out both before and after the infection of the materials, plants or seeds by the fungi.

The fungicidal compositions generally comprise between 0.1 and 95%, preferably between 0.5 and 90%, by weight of active compound.

When employed in plant protection, the amounts applied are, depending on the kind of effect desired, between 0.01 and 2.0 kg of active compound per ha.

In seed treatment, amounts of active compound of 0.001 to 0.1 g, preferably 0.01 to 0.05 g, per kilogram of seed are generally necessary.

When used in the protection of materials or stored products, the amount of active compound applied depends on the kind of application area and on the desired effect. Amounts customarily applied in the protection of materials are, for example, 0.001 g to 2 kg, preferably 0.005 g to 1 kg, of active compound per cubic meter of treated material.

The compounds I can be converted to the customary formulations, for example solutions, emulsions, suspensions, dusts, powders, pastes and granules. The application form depends on the particular intended use; it should in each case ensure a fine and uniform distribution of the compound according to the invention.

The formulations are prepared in a known manner, for example by extending the active compound with solvents and/or carriers, if desired using emulsifiers and dispersants. Solvents/auxiliaries which are suitable are essentially:

In general, the formulations comprise from 0.01 to 95% by weight, preferably from 0.1 to 90% by weight, of the active compound. The active compounds are employed in a purity of from 90% to 100%, preferably 95% to 100% (according to NMR spectrum).

The following are examples of formulations:

1. Products for Dilution with Water

A) Water-Soluble Concentrates (SL)

10 parts by weight of a compound according to the invention are dissolved in water or in a water-soluble solvent. As an alternative, wetters or other auxiliaries are added. The active compound dissolves upon dilution with water.

B) Dispersible Concentrates (DC)

20 parts by weight of a compound according to the invention are dissolved in cyclohexanone with addition of a dispersant, for example polyvinylpyrrolidone. Dilution with water gives a dispersion.

C) Emulsifiable Concentrates (EC)

15 parts by weight of a compound according to the invention are dissolved in xylene with addition of calcium dodecylbenzenesulfonate and castor oil ethoxylate (in each case 5% strength). Dilution with water gives an emulsion.

D) Emulsions (EW, EO)

40 parts by weight of a compound according to the invention are dissolved in xylene with addition of calcium dodecylbenzenesulfonate and castor oil ethoxylate (in each case 5% strength). This mixture is introduced into water by means of an emulsifier (Ultraturvax) and made into a homogeneous emulsion. Dilution with water gives an emulsion.

2. Products to be Applied Undiluted

H) Dusts (DP)

5 parts by weight of a compound according to the invention are ground finely and mixed intimately with 95% of finely divided kaolin. This gives a dustable product.

I) Granules (GR, FG, GG, MG)

0.5 part by weight of a compound according to the invention is ground finely and associated with 95.5% carriers. Customary methods are extrusion, spray-drying or the fluidized bed. This gives granules to be applied undiluted.

J) ULV Solutions (UL)

10 parts by weight of a compound according to the invention are dissolved in an organic solvent, for example xylene. This gives a product to be applied undiluted.

The active compounds can be used as such, in the form of their formulations or of the application forms prepared therefrom, e.g. in the form of directly sprayable solutions, powders, suspensions or dispersions, emulsions, oil dispersions, pastes, dustable products, preparations for broadcasting or granules, by spraying, atomizing, dusting, broadcasting or watering. The application forms depend entirely on the intended uses; they should always ensure the finest possible dispersion of the active compounds according to the invention.

Aqueous application forms can be prepared from emulsifiable concentrates, pastes or wettable powders (spray powders, oil dispersions) by addition of water. To prepare emulsions, pastes or oil dispersions, the substances can be homogenized in water, as such or dissolved in an oil or solvent, by means of wetting agents, tackifiers, dispersants or emulsifiers. However, it is also possible to prepare concentrates comprising active substance, wetting agent, tackifier, dispersant or emulsifier and possibly solvent or oil which are suitable for dilution with water.

The concentrations of active compound in the ready-for-use preparations can be varied within relatively wide ranges. In general, they are between 0.0001 and 10%, preferably between 0.01 and 1%.

The active compounds can also be used with great success in the ultra-low volume (ULV) process, it being possible to apply formulations with more than 95% by weight of active compound or even the active compound without additives.

Oils of various types, wetting agents, adjuvants, herbicides, fungicides, other pesticides and bactericides can be added to the active compounds, if need be also not until immediately before use (tank mix). These agents can be added to the preparations according to the invention in a weight ratio of 1:10 to 10:1.

The preparations according to the invention can, in the application form as fungicides, also be present together with other active compounds, e.g. with herbicides, insecticides, growth regulators, fungicides or also with fertilizers. On mixing the compounds I or the preparations comprising them in the application form as fungicides with other fungicides, in many cases an expansion of the fungicidal spectrum of activity is obtained.

-   -   a) 1.5 g of the acid (Example 2) were added to 5 ml of thionyl         chloride at 40° C. The reaction mixture was stirred until the         evolution of gas had ceased. Toluene was added to the mixture         and the solvent and excess thionyl chloride were distilled off         completely. This gave 1.6 g of a dark-green oil.     -   b) 38 mg of tert-butylamine and 58 mg of triethylamine were         initially charged in 7 ml of THF at 0° C., and 200 mg of the         acid chloride prepared beforehand, dissolved in 2 ml of THF,         were added. The reaction mixture was stirred at room temperature         for 12 h. The reaction mixture was concentrated using a rotary         evaporator, taken up in methyl tert-butyl ether and washed with         water. The organic phase was removed, dried over MgSO₄ and         concentrated. The crude product was purified by preparative         HPLC.
